Choosing the Right PE Protective Cable for Home Switchboard Earthing Connection

Hello.
I have a question how to use the PE cable to connect the earthing pin (outside the building) to the busbar of the home switchboard.
The connection is made of a YKY 5x10 mm2 cable.
I want to do grounding additionally, because I am not convinced by this piece of flat bar (rod) in the ground in the ZE cabinet.
I want to make a grounding with a few pins and a hoop at a depth of about 1m.
But I don't know if I have to buy some YKY and use 1 wire as PE, or maybe there are typical cables for grounding.

Start by presenting the connection conditions (network type, installation parameters). It is not really necessary to ground the N and PE split point. And if you want to do grounding, first of all, let it meet the technical conditions enabling it to work because

the system is TNC and I have to switch to TNS. The connection of N with PE with a piece of rod (1m) in the ground was made in the ZE cabinet. For me, the most important thing is safety and I am going to connect several RCDs in the house. Measurements will of course be taken. I am only interested in whether it is possible to buy a PE cable for laying in the ground

You leave the ground with a galvanized hoop and then LGYżo from 16 mm ^ 2 and above is used for this purpose.

But the LGYżo cable from 16 mm ^ 2 cannot be placed in the ground!
I will have a length of cable about 2 meters from the distribution board and then 2 meters in the ground to the pin with the hoop

Read again my colleague Karolq's post. You put a hoop in the ground, and connect it to the LgYżo wire above.

I only have the entrance to the building underground and therefore this cable will be about 2 meters in the ground.

Then you enter the building with a rope.

So what technical conditions are we talking about?
And what are the guarantees of an appropriate ground resistance?

Why do you call a single strand a cable?
And why should it not be placed in the ground?

a hoop for a residential building? I have big doubts
On the other hand, stranded, cable in the ground is exposed to difficult conditions.
I could not find the YKY 1x16 protective cable in the specification (colors). I wonder if anyone had a similar problem

There was a similar topic https://www.elektroda.pl/rtvforum/topic1890515.html
In post No. 20 I presented a solution for which you seem to opt for a friend sebtr but you are defending yourself.

My friend . The protective grounding at the facility is absolutely necessary. You introduce the cooperage into the basement and connect it to the PE rail.
Buddy darek_wp - there is no question of grounding the separation point anywhere. From what the author of the post writes, the installation in TN-S enters the facility and the colleague additionally grounds the PE wire. I rather advise against connecting the LGY cable underground.

Of course, copper cables should not be laid in the ground as well. And you can't even think about combining them.

However, the basic question for the author of the thread:
What is the purpose of splitting the PEN in a junction remote from the object?
Why is there no foundation earth electrode (if it is a new building, of course)?

When it comes to a new building, I advise you to get out of your head with some high heels.
In accordance with the applicable rules of technical knowledge and the construction design, it should be carried out (as mentioned in col. kkas12 ) foundation earth electrode.
If it is not there, then in order to equip the building with proper equipotentialization, it is necessary to dig a rim, not to mention its earthing value in the case of using overvoltage protection.

Hello.

I don't understand what the dispute is about. About the name?
After all, there is the name "protective conductor"
Bezel clearly writes about it
And it's all in PN-HD 60364-5-54: 2010 Electrical installations in building structures. Selection and assembly of electrical equipment.

Probably a colleague wondered why ZE performs the PEN distribution and wants the recipient to have TN-S in the contract. It is probably mainly about securing the measuring system and the position in the meter cabinet.
This earth electrode (short flat bar, rod under the box) is not suitable as an earth electrode. I agree that the best earth electrode is undoubtedly the foundation earth electrode, but unfortunately, most people forget about the implementation of the foundation earth electrode at the construction stage. Now, when it is time to make the correct earth electrode, I have to bury the hoop under the connection (YKY 5x10mm2 cable) and lead it to the building. The problem is how to bring the hoop to a building without a basement. Making an additional Lgy connection box is a solution, but I'm wondering where to put a box that is undoubtedly disfiguring. Another solution is to lead the hoop to the clamp of the earthing bar to the bar, but this requires additional forging in the wall.

What does forgetting mean and what does most mean?
If someone is building for himself WITHOUT any building supervision, it is to himself.
If a construction manager was employed by the investor and he did not ensure it, the manager should be dismissed without remuneration.
It performs independent functions, so that he knows himself, that he knows what he writes in paragraph 184 of the Regulation of the Minister of Infrastructure on technical conditions,
which buildings and their location should correspond to of April 12, 2002 (Journal of Laws No. 75, item 690).

For doubters, I present photos of the BEDNARKA approach to the interior of the building [single-family house]:



Ending of the hoop with GSW rail [the same building]:



If I searched, I would probably find more photos. The fact that few people have such installations does not mean that they are done wrong ...

@ele_pp the fact is that even the supervision does not remember about the foundation earth electrode, which is the easiest way to make, no matter if artificial or natural, and few people visit the electrician before the shell is closed ...

What are the regulations, everyone knows what they are reflected in reality, you know ... since there are no earth electrodes even on the projects ...

I close the topic
